Boundary-layer stability and laminar-to-turbulent transition are examined on the BOLT flight geometry using predicted flow conditions at ascent and descent flight times. The parabolized stability equations technique is used predominantly for this analysis as it has proven to be efficient and accurate in modeling the transition process on other three-dimensional geometries. The various potential transition mechanisms are identified and their linear amplification is discussed. These mechanisms include second-mode and crossflow instabilities. Since the potential mechanisms of BOLT and HIFiRE-5b align, a study that directly compares two different geometries at the same flow conditions is completed.
